Time To First Byte and proxy_buffering

[Jonathan Matthews]

Hi all -

Does "proxy_buffering on" (especially when it'll definitely buffer to
disk) imply that the client will *not* be sent the first part of the
response until nginx has received and buffered the entire response
from the upstream server? Or does/can the upstream response buffering
happen in parallel with the client-side response being sent?

Many thanks,
Jonathan
